Phoenix Audio DRS-8 Mk2 - 8 Channel Class A Microphone Pre-Amplifier - Manual (Page 3)

Controls and descriptions:
Front Panel:
Input Sens Switch:
The Input sensitivity switch is a rotary 9 position switch. It is marked from -30 to
-70. This controls the gain for the INPUT stage in 5dBu steps.
The switch applies gain at all times and does not disconnect when using the Mic/Line switch. It
affects
both the XLR and 1/4” jack inputs (see rear panel inputs) at once.
Mic/Line switch: The Mic/Line switch allows the use of Mic or Line level inputs. The
input is in LINE mode when the switch is pressed in.
+48V switch: The +48V switch applies industry standard 48V Phantom power to the
input
XLR/1/4” jack. NOTE: The phantom power will be applied to BOTH the XLR
connections AND the 1/4” Jack at the same time. Make sure the switch is OFF when
using LINE inputs.
PH switch: The PHase switch will reverse the PHase of the INPUT signal when pressed
in.
HPF switch: The High Pass Filter switch applies a filter to the INPUT signal when
pressed in. This is useful for eliminating low-level/frequency background hum from
equipment such as noisy Air Conditioning units.
Mute switch: The Mute switch will mute the channel when pressed in.
Level LED's: The LED meter is connected to the OUTPUT of each channel. This
indicates levels being sent from the OUTPUT XLR on the channel and is useful for
monitoring levels being sent to other equipment. The meter has some hysteresis to
make it easier to see fast peaks in the signal.
O/P Level control: The Output level control is a rotary control. This affects the OUTPUT level
being sent to the OUTPUT XLR's and the Monitor D-sub connector. The resulting level will be
shown on the LED Meter.
Monitor Selector switch: The monitor selector switch is an 8 position rotary selector
switch.
The switch selects each channel (one at a time) and sends it to the Output Jack on the
front panel.
Monitor Output Jack: The monitor Output Jack is a 1/4” Mono Jack socket. This can
be used to send the monitor signal directly to headphones or a monitoring system.
Mon Level control: The Monitor level control is a rotary control and adjusts the output
level at the 1/4” Monitor Output Jack socket.
Rear Panel
Mains Input Connector: The mains input is via an industry standard IEC “Kettle
lead” input with integrated fuse carrier (500mA Quick Blow fuse). Special attention
should be paid to the mains input voltage.
V-Sel Switch: The voltage selector switch MUST be set to correspond with the mains
voltage in your area.
